 Are the lights on, on the switch's ports that you are using?   Have you
 rebooted the switch?   Are you able to connect with other machines or
 ports (say  a laptop)?  Is the light working on the nic?  Cabling good?
 If you have multiple nics you should stop/start them and see if you can
 get one to work, sometimes one works when another won't.  service network
 stop, ifup eth0, ifup eth1, etc.   Look at your dmesg and see whether it
 finds your eth0 or eth1, that'd be nice to know....

 If you are able to narrow it down to the one FC2 box (and within the os),
 then I would say that lastly you should run a chkrootkit utility on the
 box to see if you have been own3d.

 I ran chrootkit and I found this:

 Checking `bindshell'... INFECTED (PORTS:  1524 31337)
 Checking `lkm'... You have    12 process hidden for readdir command
 You have    12 process hidden for ps command
 Warning: Possible LKM Trojan installed

 This looks like a problem!!  What is bindshell?  I did a locate but could
 not find it installed.  What do I need to do?

 TIA
 Cheers
 Marc

 It appears as though you have been hacked aka 0wn3d :) You better back up
 your data and rebuild the system.


As a followup, can you telnet to the ports indicated, and what do you see?
